Design Patterns in C#: Observer

Learn everything there is to know about the Observer Design Pattern

About This Course

The Observer Design Pattern is a fundamental design pattern in software engineering, commonly used to create a one-to-many relationship between objects so that when one object changes state, all its dependents are notified and updated automatically. This pattern is essential for developers, as it promotes a loosely coupled system where components can react to changes dynamically. The Observer pattern is particularly valuable in applications requiring real-time updates, such as in user interfaces, event-driven systems, or data streaming. In this course, Amichai Mantinband will teach you everything you need to know to implement the Observer pattern, enabling you to build responsive, flexible, and scalable applications.
